A New Level in the Torpedo Ecosystem: From C.A.B. to Opus
With the Opus, Two Notes extends the DNA of the Torpedo pedals renowned for their DynIR cabinet simulation by adding a true "full amp" approach through TSM modeling. The idea is simple: to recreate the feel of a tube preamp and power amp while maintaining the precision and flexibility of the cabinet simulation that has become the brand's signature.
Who It's For, Which Styles, and In What Contexts?
The Opus is aimed at guitarists (and pedalboard users) who want professional sound direct: recording, silent rehearsal, live with in-ear monitors, or as a clean/platform edge-of-breakup base to stack your overdrives and fuzz pedals. From detailed clean tones to high-gain saturation, including more "British" flavors, it fits equally well in a small minimalist pedalboard or a full MIDI setup.
Controls, Simulation Engines, and Workflow
At the heart of the Opus, the TSM amp section offers 5 preamp emulations, complemented by a power amp simulation with 4 tube models (6L6, EL34, EL84, KT88). You can shape the response via Pentode/Triode architectures and Push-Pull (Class AB) or Single Ended (Class A) topologies. On the cabinet side, the DynIR allows for dual microphone capture, access to 8 mics per cabinet, and 12 room simulations, enabling you to switch from a tight, close sound to a wider, mix-ready image.
To finalize, a set of DSP tools is integrated: equalizer, enhancer, noise gate, and reverb. The Opus features 99 preset slots and a collection of DynIR cabinets from the Opus series (32 cabinets), including captures associated with Steve Stevens, Dave Friedman, Pete Thorn, George Lynch, and Phil X.
The Sound
The Opus's sonic signature is based on an "amp" playing feel: precise attack, pick-responsive dynamics, and saturation that cleans up naturally depending on your volume and touch. The DynIR engine provides realistic depth (mic placement + room) and definition that helps you quickly find a mix-ready sound, whether modern and tight or more open and organic.

I had read reviews and seen rave videos about this French product (but made in China which largely explains the very correct price).
After a week of use, I totally agree with these opinions.
Two Notes is doing a great job; keep it up.
I even use it behind a Helix because the cabinet simulations seem much better to me with the Torpedo CAB M+.
In addition, whether it is the control software (torpedo remote) or the plug-in (Wall Of Sound), the interfaces are intuitive and pleasant to use.
Be careful, however, this is not a product for someone who is just starting out (in my opinion), because you have to have formed a culture and a musical ear to really appreciate the possibilities and differences in sound. Or maybe be accompanied by someone to experiment to develop this culture precisely.
Next purchase for me: the 8 Ohm captor for my tube amp. I have no doubt that I will find an excellent product.Automatically translated

What to say? It's of great quality, the sounds are great...
Between the current offer, the “welcome” bags (for registering) and the 5 I bought (including one free!) I end up with 90 DynIR cabinets of very high quality!
I was used to the more “classic” IRs, now it's a level higher.
Played in clean sound only for now, jazz guitar plugged into the M+ cab, Polytone emulation (jazz club or jazzbox), a bit of reverb... and that's the thing.
If you need to amplify it, simply plug it into the Guitar Sound System Jazz Cat (GSS 05G200SJC) for a portable solution, of excellent quality, and made in France.Automatically translated

Perfect, the value for money is unbeatable. The construction is solid, the HW interface easy to use. the software is undoubtedly a bit perfectable (it is not possible to use without registering your hardware so I suppose that at the first start it is not possible to be offline) and the HW is only recognized as activated after restarting the software (this is a bug, and therefore the gears included are not accessible before this restart).

A huge sound arsenal in a tiny and very affordable package. Two Notes achieves the feat of combining its DynIR speaker technology with realistic amp simulation: plugged into a quality FRFR cab, you find the feeling of real amps, without the clutter or the cost.
The app is just fantastic: simple, intuitive, effective...Automatically translated

Nice little machine that gives sounds that are sometimes average, but often very good.
I noticed small instabilities (especially with Bluetooth) that required the opening of a ticket with Two Notes. This was quickly fixed by sending a new firmwareAutomatically translated

Can custom impulse responses be loaded into this pedal?
IR loading is supported with a dual static IR loader and an acoustic DI. More than 40 acoustic impulse responses are included.
Is the Torpedo Remote app compatible with a computer and a smartphone?
Torpedo Remote works on iOS, Android, macOS, and Windows, via USB or wireless. Editing settings, managing presets, and real-time monitoring of over 600 DynIR speakers are available.
